Of the nixed spacewalk, Brando Dean, from NASA’s public affairs office, told CNN (back in March), “We do our best to anticipate the spacesuit sizes that each astronaut will need, based on the spacesuit size they wore in training on the ground.” Dean continued, “However, individuals’ sizing needs may change when they are on orbit, in response to the changes living in microgravity can bring about in a body. In addition, no one training environment can fully simulate performing a spacewalk in microgravity, and an individual may find that their sizing preferences change in space.”

Another NASA public affairs rep, Stephanie Schierholz, also told CNN, “You want it to be as optimally fitted as possible. So the feedback from Anne was that she felt she should really be in a medium suit. There’s another medium torso but it’s not currently configured into a spacesuit. So it’s easier to swap out the spacewalkers than to swap out parts of the spacesuit.”
